Where is the coldest known place in the Universe? It may sound strange, but today, it is here on Earth: in 1995, in a laboratory in M.I.T. (Massachusetts Institute of Technology), the German physicist Wolfgang Ketterle and his colleagues have cooled a sodium gas to the lowest temperature ever recorded, only half-a-billionth of a degree above absolute zero.

But, soon, this record will be broken. NASA is going to launch a facility to the International Space Station (ISS) that will contain a spot 10 billion times colder than the outer space. The new Cold Atom Laboratory (CAL) facility, which will operate in microgravity, could help answer some big questions in modern physics, allowing researchers to dive deep into the quantum realm in a way that would never be possible here on Earth.

The hottest place in the Universe exists here on Earth, like the coldest place in the Universe. Both these extreme temperatures are not natural, they are human-made. The coldest temperature was achieved in the German physicist and professor of physics Wolfgang Ketterle’s laboratory at the Massachusetts Institute of Technology (MIT). The hottest temperature, also recognized by the Guinness Book of World Records, was achieved at CERN’s Large Hadron Collider (LHC).

On 13 August 2012 scientists at CERN’s Large Hadron Collider, Geneva, Switzerland, announced that they had achieved temperatures of over 5 trillion K and perhaps as high as 5.5 trillion K (more than 9.9 trillion °F). The team had been using the ALICE experiment to smash together lead ions at 99% of the speed of light to create a quark-gluon plasma – an exotic state of matter believed to have filled the universe just after the Big Bang.

Crocodiles (subfamily Crocodylinae) or true crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Although they are big, they suffer from a prevalence of “big fish” stories and over-exaggeration. In the Internet age, photographs of crocodiles manipulated digitally to make the animal look much larger than it is. So, how big the largest crocodiles are actually? Here are the top 10 largest crocodiles ever recorded.

It may sound strange, but the coldest place in the Universe is not anywhere in the vast, cold outer space – it exists here on Earth. Well, it is not actually a natural place you can come across. It is in a laboratory in M.I.T. (Massachusetts Institute of Technology).

Like crocodiles, snakes also suffer from a prevalence of “big fish” stories and over-exaggeration in the internet era. In fact, it is very difficult to measure how large actually a snake is, especially if it’s really big. So, how big are the largest snakes actually?

If you search for the fastest land animals on the Internet, you will find many “fastest animals” lists, most of them are popular “top list” sites. But, in fact, there is a tendency to overestimate the speed of fast animals. Even the speed of the world’s fastest land animal, cheetah’s speed is usually highly overestimated.

Measuring an animal’s speed is a very hard task, and very few of them were properly authenticated. Some of them are really fast, that’s true, but what is the exact number? This information is usually not measured correctly.

Earth is still the only planet we know where water can exist in liquid form on the surface and the water is vital for all known forms of life. Rain brings life: it is a major component of the water cycle (also known as the hydrologic cycle, the continuous movement of water on, above and below the surface of the Earth) and is responsible for depositing most of the fresh water on the Earth. Here are the top ten wettest places on Earth.

Ligers are the largest cats on Earth. A liger can be more than 900 pounds (~408 kg) in weight and 12 feet (~3.65 m) long, weighing almost 100 times more than house cats and almost twice as much as either Panthera tigris (tiger) or Panthera leo (lion).

The liger, the largest of all known extant felines, is a hybrid cross between a male lion and a female tiger.
